Log On
You only applied the -2 exponent to the denominator, when the square brackets are around the entire fraction. That is to say, your answer would have been (almost) correct if you had started with:
So, first apply the following rule:
Giving you:
Next apply:
(Which you did correctly where you applied it) Giving you:
But you still have one more step, and this is why I added the parenthetical almost earlier:
